Not worth it
I got 10000 points and used them to buy two £10 Asda gift cards. The gift cards arrived but when I tried to use them they had no money on them - this was embarrassing as I help up a line of shoppers while the store tried in vain to find out what was wrong. I tried complaining but the only email contact put me through to their US based customer service who signposted me back to the same starting point I'd started from. After this I gave up as I'm busy and can't waste time chasing after £20 of vouchers in a system that appears designed to make communication and correction of errors as difficult as possible.
